CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 14/500,990, filed Sep. 29, 2014, which claims the benefit of U.S. Provisional Application No. 62/005,791, entitled “METHODS AND SYSTEM FOR MANAGING PREDICTIVE MODELS” filed May 30, 2014, the contents of both of which are incorporated herein by reference in their entireties for all purposes.

FIELD

The described embodiments set forth a technique for establishing, deploying, and updating predictive models across different computing devices.

BACKGROUND

Recent years have shown a proliferation in the number of individuals who own and operate mobile computing devices (e.g., smartphones and tablets). Typically, an individual uses his or her mobile computing device to carry out different types of activities throughout the day, e.g., placing phone calls, sending and receiving electronic messages, accessing the internet, and the like. These activities are highly personalized and specific to the individual, and, as a result, a pattern of behavior typically exists within the scope of each application that the individual accesses on his or her mobile computing device. For example, within a messaging application on an individual's mobile computing device, there typically exists a pattern among the contacts with whom he or she regularly communicates. These patterns present an opportunity for application designers to preempt an individual's habits and to dynamically adjust to provide an enhanced overall user experience. Such dynamic adjustment can include, for example, updating the manner in which content is displayed, suggesting input for the individual, recalling the individual's preferences, and the like.

Typical approaches used to implement dynamic adjustment are piecemeal at best. More specifically, when application developers desire to enhance their applications with dynamic adjustment capabilities, they are imposed with the difficult task of building frameworks that can identify and respond to individuals' behavioral patterns. Consequently, these frameworks often deliver inaccurate and undesirable functionality, which can frustrate individuals and degrade their overall user experience. Moreover, these frameworks can be inefficient with respect to the rate at which behavioral patterns are identified and to which they are adjusted. Such inefficiency can degrade the battery performance and overall responsiveness of mobile computing devices, especially when application developers fail to design the frameworks to identify appropriate times to carry out management tasks.

SUMMARY

Representative embodiments disclosed herein set forth a framework that enables application developers to enhance their applications with dynamic adjustment capabilities. Specifically, the framework, when utilized by an application on a mobile computing device that implements the framework, can enable the application to establish predictive models that can be used to identify meaningful behavioral patterns of an individual who uses the application. In turn, the predictive models can be used to preempt the individual's actions and provide an enhanced overall user experience. The framework is configured to interface with other software entities on the mobile computing device that conduct various analyses to identify appropriate times for the application to manage and update its predictive models. Such appropriate times can include, for example, identified periods of time where the individual is not operating the mobile computing device (e.g., at night when the individual is sleeping), as well as recognized conditions where power consumption is not a concern (e.g., when the mobile computing device is plugged-in). Thus, the framework reduces the burden with which application developers are conventionally faced when attempting to produce applications that are capable of evolving to complement individuals' different behavioral patterns.

DETAILED DESCRIPTION

Representative applications of apparatuses and methods according to the presently described embodiments are provided in this section. These examples are being provided solely to add context and aid in the understanding of the described embodiments. It will thus be apparent to one skilled in the art that the presently described embodiments can be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the presently described embodiments. Other applications are possible, such that the following examples should not be taken as limiting.

The embodiments disclosed herein set forth a framework that enables application developers to utilize predictive models to enhance their applications. According to one embodiment, the framework can be implemented as an application programming interface (API) that includes a set of commands for establishing, deploying, and updating predictive models across applications executing on mobile computing devices. Specifically, the framework can enable developers to manage predictive models using a variety of approaches that are tailored to the specific natures of different applications. The framework can also identify appropriate times for applications to manage and update their predictive models in accordance with new training data that is available for processing.

In some cases, establishing a reliable predictive model requires intensive processing to be performed on a large set of training data. Consider, for example, a predictive model that is directed toward identifying a gender of an individual based on his or her height and shoe size. To establish this predictive model, it may be necessary to process tens of thousands of training data samples in order to identify a trend among the training data samples. Notably, carrying out this processing can be expensive in terms of energy and time consumption, which makes particular hardware platforms—such as a smartphone or a tablet—impractical for establishing the predictive model. Accordingly, one embodiment set forth herein involves establishing a predictive model at a source computing device (e.g., a server computing device, a desktop computing device, a laptop computing device, etc.), and then distributing the predictive model to destination computing devices (e.g., smartphones, tablets, wearable computers, car interfaces, etc.) that are configured to utilize the predictive model. Specifically, the source computing device first establishes a raw predictive model based on a set of training data, and then identifies different types of destination computing devices (e.g., a smartphone and a tablet) that will utilize the predictive model. In turn, the source computing device can establish, for each type of destination computing device, a “deployment” predictive model that is specifically tailored to the configuration (i.e., software and hardware capabilities) of the destination computing device. This beneficially enables the predictive model to be utilized by each type of destination computing device in an optimized manner. The source computing device can alternatively—or additionally—establish a generic predictive model—such as the raw predictive model—that can be distributed to destination computing devices. In turn, each destination computing device can process the generic predictive model to establish a deployment predictive model that is specific to the configuration of the destination computing device.

The generation of a deployment predictive model that is specific to a destination computing device can be accomplished using a variety of approaches. One approach, for example, can involve generating the deployment predictive model for an optimized load time on the destination computing device. In this example, the raw predictive model is generated and stored in a platform-independent form (e.g., raw text, extensible markup language (XML), etc.). Notably, if this platform-independent form of the raw predictive model were utilized by a destination computing device with limited computing power, the destination computing device would likely incur a large delay when parsing the raw predictive model to establish a form of the model that can be utilized by the destination computing device. To cure this deficiency, the raw predictive model can be deployed as a binary version that is specifically tailored to the destination computing device so that the destination computing device is not required to carry out a parsing function each time the model is utilized.

Another approach can involve generating the deployment predictive model that is based on a machine architecture of the destination computing device. Notably, destination computing devices may vary in aspects such as 64-bit versus 32-bit central processing units (CPUs), ARM® architecture versus Intel® architecture, alignment of binary data structures (as caused by changes to compilers), and the like. Accordingly, the deployment predictive model can be generated such that it is suitable and optimized for deployment on the target architecture of the destination computing device. This can include, for example, utilizing tiling matrices for the appropriate size of a data cache on the CPU, changing the “resolution” of models, implementing larger filters, and the like.

Yet another approach can involve generating the deployment predictive model based on a software platform being utilized by the destination computing device. Specifically, destination computing devices may vary in aspects such as the type of local database that is available (e.g., SQLite® versus proprietary storage formats). Accordingly, the deployment predictive model can be generated such that it is suitable and optimized for compatibility with the different software platforms that are implemented on the destination computing device.

Accordingly, the foregoing distribution scheme provides an efficient approach for deploying predictive models that require infrequent updates to maintain their relevancy and accuracy. In some cases, however, it is desirable for predictive models to periodically be updated at a mobile computing device in order to maintain relevancy and accuracy. Consider, for example, a predictive model that is directed toward preempting messaging habits (e.g., group messaging preferences, auto-correction preferences, etc.) of an individual who operates the mobile computing device. According to this example, it is beneficial to periodically update the predictive model based on updated training data that is gathered over time as the individual transmits messages using the mobile computing device. Such periodic updates can enable the predictive model to provide useful information, e.g., social networking-based observations derived from observing group messaging preferences. Accordingly, one embodiment set forth herein involves periodically updating a predictive model at a mobile computing device. In some cases, the aforementioned framework can be configured to identify a particular time at which the predictive model should be updated. This particular time can include, for example, a known time where the mobile phone is dormant (e.g., night time) and where the mobile phone is being charged. When the particular time is identified, the mobile computing device processes an updated set of training data associated with the predictive model. Next, the mobile computing device implements the updated predictive model for usage on the mobile computing device, and updates a configuration to reflect that the updated set of training data has been processed.

Accordingly, the foregoing distribution scheme provides an efficient approach for periodically updating a predictive model at a mobile computing device. In some cases, however, it is desirable for predictive models to continuously (instead of periodically) be updated at a mobile computing device. Consider, for example, a predictive model that is directed toward preempting email habits (e.g., frequent addressees, VIP contacts, etc.) of an individual who operates the mobile computing device. In this example, if a large number of emails are downloaded from a server (e.g., when the mobile computing device is purchased), it can be beneficial for the predictive model to be immediately established and updated instead of holding off until a later time (as with the periodic approach set forth above). In this manner, the predictive model can immediately be used to provide relevant and useful preemptive features to the individual. Accordingly, one embodiment set forth herein involves continuously updating a predictive model at a mobile computing device. Specifically, when a threshold amount of additional training data has been gathered, the mobile computing device updates the predictive model based on the additional training data. The mobile computing device then implements the updated predictive model for usage on the mobile computing device, and updates a configuration to reflect that the additional training data has been processed. It is noted that the repetition of this process can be based on a variety of factors, e.g., after a period of time has lapsed, after a threshold amount of new training data has been gathered, and the like.

Additional embodiments set forth herein are directed toward increasing efficiency and performance when managing predictive models on mobile computing devices. Specifically, one embodiment involves enhancing the manner in which predictive models are cached on mobile computing devices. Predictive models can be complex in nature and require a considerable number of rows and fields when being mapped from a file (when stored) to a database (when being processed), and vice-versa. Thus, it is beneficial to eliminate the necessity to re-perform the mapping each time the predictive model is updated. Accordingly, one embodiment set forth herein involves caching a predictive model into a memory of the mobile computing device, where the predictive model is stored as a contiguous file within the memory. When a threshold amount of training data associated with the predictive model is gathered, the predictive model is retrieved from the memory. Given the contiguous structure of the predictive model, the process by which the predictive model is updated is simplified, and the amount of work that is typically required to map the predictive model into a database is significantly reduced. The predictive model is then updated, and cached back into the memory using the same contiguous file approach.

Accordingly, the foregoing approaches provide techniques for establishing, deploying, and updating predictive models across different computing devices. A more detailed discussion of these techniques is set forth below and described in conjunction with FIGS. 1A, 1B, 1C, and 2-7, which illustrate detailed diagrams of systems and methods that can be used to implement these techniques.

FIG. 1A illustrates a block diagram of different components of a system 100 that is configured to (1) establish a predictive model at a source device (e.g., a server), and then (2) distribute the predictive model to destination devices (e.g., smartphones) that are configured to utilize the predictive model, according to one embodiment. As shown in FIG. 1A, a source device 102—which can represent a server computing device, a desktop computing device, a laptop computing device, etc.—accesses training data 104, and processes the training data 104 using a training algorithm 106 to produce a raw predictive model 108. In turn, the source device 102 identifies the different types of destination devices 114 (e.g., smartphones tablets, wearable computers, car interfaces, etc.) to which the predictive model will be deployed. Specifically, a type of a destination device 114 can be defined by a hardware platform and/or a software platform utilized by the destination device 114, the performance capabilities of the destination device 114, and the like. These factors can be used to help determine optimized structures for the predictive models when implemented on the destination devices 114.

When the source device 102 identifies the destination devices 114, the source device 102 establishes deployed predictive models 110 that are transmitted to the destination devices 114 (over a network 112) and implemented on the destination devices 114. Alternatively, the source device 102 can distribute the raw predictive model 108 to the destination devices 114, whereupon each of the destination devices 114 can process the raw predictive model 108 to establish a deployed predictive model 110 that is optimized for the destination device 114. As shown in FIG. 1A, and within the context of a destination device 114, a deployed predictive model 110 can be associated with one or more applications 115 that execute on the destination device 114. In turn, the application 115 can establish prediction/runtime information 118 that enables the application 115 to carry out preemptive features aimed to enhance an individual's overall user experience when operating the destination device 114. Accordingly, the distribution scheme set forth in FIG. 1A provides an efficient approach for deploying predictive models that require infrequent updates to maintain their relevancy and accuracy.

FIG. 1B illustrates a block diagram of different components of a system 150 that is configured to establish and periodically update a predictive model at a client device, according to one embodiment. As shown in FIG. 1B, a client device 151 can include applications 152 that are configured to utilize predictive model API calls 154 to access a predictive model API framework 158 that is available on the client device 151. Specifically, the predictive model API calls 154 can enable the applications 152 to perform a variety of operations associated with establishing and/or managing predictive models at the client device 151. For example, as shown in FIG. 1B, an application 152 provides training data 156 to a training algorithm 160 included in the predictive model API framework 158. In turn, the training algorithm 160 produces a raw model 162, which is then converted to a deployed predictive model 164. Again, the deployed predictive model 164 can be optimized for the client device 151 based on the capabilities of the client device 151. Once the deployed predictive model 164 is established, the deployed predictive model 164 is provided to the application 152 for implementation. In turn, the application 152 can establish prediction/runtime information 168 that enables the application 152 to carry out preemptive features aimed to enhance an individual's overall user experience when operating the client device 151.

As noted above, it can be desirable to periodically update the deployed predictive model 164 when additional training data 156 is gathered by the application 152. Such additional training data 156 can be gathered, for example, over time as the application 152 is utilized by an individual. To identify appropriate times at which to update the deployed predictive model 164, the predictive model API framework 158 interfaces with a resource manager 170 that is available to the client device 151. Specifically, the resource manager 170 is configured to monitor various aspects of the client device 151 to identify the appropriate times. The resource manager 170 can monitor these aspects by utilizing other software entities available to the client device 151, including a battery manager 172 and an event manager 174. The battery manager 172 can indicate power-related metrics to the resource manager 170, including a current charge level of a battery included in the client device 151, an average rate at which the charge level of the battery declines, whether or not the client device 151 is plugged-in to a power outlet and is charging, and the like. The event manager 174 can track the manner in which activities take place within the client device 151 in order to identify periods of time where the individual is not utilizing the client device 151 (e.g., late at night). Accordingly, the predictive model API framework 158 can remain in communication with the resource manager 170 to identify times at which predictive models should be updated. In turn, the predictive model API framework 158 can interface with the applications 152, gather updated training data 156 to perform updates to predictive models, and deploy updated predictive models to the applications 152.

FIG. 1C illustrates a block diagram of different components of a system 180 that is configured to continuously update a predictive model at a client device 151, according to one embodiment. As shown in FIG. 1C, and described above in conjunction with FIG. 1B, the client device 151 can include applications 152 that are configured to utilize predictive model API calls 154 to access a predictive model API framework 158 that is available on the client device 151. As noted above, it can be desirable to continuously update a deployed predictive model 164 as additional training data 156 is gathered by the application 152 in conjunction with previously-established prediction/runtime information 168. Such additional training data 156 can be gathered, for example, over time as the application 152 is utilized by an individual. Although, in this example, the predictive model API framework 158 is configured to continuously update the deployed predictive model 164, the predictive model API framework 158 can optionally interface with the resource manager 170 to identify appropriate times at which to perform the updates to the predictive models. For example, the predictive model API framework 158 can interface with the resource manager 170 to ensure that updating the deployed predictive model 164 will not interfere with critical functions of the client device 151 when being operated by an individual (e.g., when in a phone call or when watching a video). In either case, the predictive model API framework 158 can continuously interface with the applications 152, gather updated training data 156 to perform updates to predictive models, and deploy updated predictive models to the applications 152.

Accordingly, FIGS. 1A, 1B, and 1C illustrate different approaches for establishing, deploying, and updating predictive models across different computing devices. FIGS. 2-3 are provided to supplement the embodiment set forth in FIG. 1A. In particular, FIG. 2 illustrates a method 200 for generating and deploying predictive models to computing devices, according to one embodiment. Specifically, FIG. 2 coincides with the embodiment of FIG. 1A set forth above that involves establishing a raw predictive model at a source computing device and distributing the raw predictive model to destination computing devices, whereupon the destination computing devices convert the raw predictive models into deployment predictive models based on their configurations. As shown in FIG. 2, the method 200 begins at step 202, where the source device 102 receives a request to generate a raw predictive model based on a set of training data. At step 204, the source device 102 generates the raw predictive model based on the set of training data. At step 206, the source device 102 identifies one or more destination computing devices to which the raw predictive model is to be deployed. At step 208, the source device 102 distributes the raw predictive model to the one or more destination computing devices.

FIG. 3 illustrates a method 300 for generating and deploying predictive models to computing devices, according to one embodiment. Specifically, FIG. 3 coincides with the embodiment of FIG. 1A set forth above that involves, at a source device, converting a raw predictive model into deployment predictive models, and distributing the deployment predictive models to destination computing devices. As shown, the method 300 begins at step 302, where the source device 102 receives a request to generate a raw predictive model based on a set of training data. At step 304, the source device 102 generates the raw predictive model based on the set of training data. At step 306, the source device 102 identifies one or more destination computing devices to which the raw predictive model is to be deployed. At step 308, the source device 102, for each of the one or more destination computing devices, and using the raw predictive model: (i) generates a deployment predictive model that is specific to the destination computing device, and (ii) provides the deployment predictive model to the destination computing device.

Additionally, FIG. 4 is provided to supplement the embodiment set forth in FIG. 1B. In particular, FIG. 4 illustrates a method 400 for periodically updating a predictive model at a mobile computing device, according to one embodiment. As shown, the method 400 begins at step 402, where the predictive model API framework 158 identifies a condition to perform an update to a predictive model. At step 404, the predictive model API framework 158 accesses an updated set of training data on which to base the update to the predictive model, where the updated set of training data supplements an original set of training data previously used to establish the predictive model. At step 406, the predictive model API framework 158 updates the predictive model based on the updated set of training data. At step 408, the predictive model API framework 158, subsequent, to updating the predictive model: (i) implements the predictive model for usage, and (ii) updates a configuration to reflect that the updated set of training data has been processed.

Additionally, FIG. 5 is provided to supplement the embodiment set forth in FIG. 1C. In particular, FIG. 5 illustrates a method 500 for continuously updating a predictive model at a mobile computing device, according to one embodiment. As shown, the method 500 begins at step 502, where the predictive model API framework 158 identifies that a threshold amount of additional training data has been added to a set of training data on which a predictive model is based. At step 504, the predictive model API framework 158 determines, based on parameters associated with the predictive model, an appropriate time to update the predictive model. At step 506, the predictive model API framework 158, at the appropriate time, updates the predictive model based on the additional training data. At step 508, the predictive model API framework 158, subsequent to updating the predictive model, implements the predictive model for usage.

As previously noted herein, additional approaches can be implemented to optimize then manner in which the predictive models are stored on the different computing devices. For example, a mobile computing device can be configured to store a predictive model in a contiguous file so that it is not necessary to reconstruct and deconstruct the predictive model each time the predictive model is read from and stored into memory. Accordingly, FIG. 6 illustrates a method 600 for caching a predictive model into a memory of the mobile computing device, where the predictive model is stored as a contiguous file within the memory, according to one embodiment. As shown, the method 600 begins at step 602, where the predictive model API framework 158 caches a predictive model into a memory of a mobile computing device, where the predictive model is stored as a contiguous file within the memory. At step 604, the predictive model API framework 158 establishes a set of training data that is specific to the predictive model. At step 606, the predictive model API framework 158 identifies a time at which to update the predictive model based on the set of training data. At step 608, the predictive model API framework 158 retrieves the predictive model from the memory. At step 610, the predictive model API framework 158 updates the predictive model based on the set of training data. At step 612, the predictive model API framework 158 caches the predictive model into the memory.

A data bus 716 can facilitate data transfer between at least a storage device 740, the processor 702, and a controller 713.
